## Rank

sage: E.rank()

The elliptic curves in class 9450.ca have rank $$0$$.

## Modular form9450.2.a.ca

sage: E.q_eigenform(10)
$$q + q^{2} + q^{4} - q^{7} + q^{8} - 6q^{11} - 5q^{13} - q^{14} + q^{16} + 6q^{17} + 2q^{19} + O(q^{20})$$

## Isogeny matrix

sage: E.isogeny_class().matrix()

The $$i,j$$ entry is the smallest degree of a cyclic isogeny between the $$i$$-th and $$j$$-th curve in the isogeny class, in the LMFDB numbering.

$$\left(\begin{array}{rr} 1 & 3 \\ 3 & 1 \end{array}\right)$$

## Isogeny graph

sage: E.isogeny_graph().plot(edge_labels=True)

The vertices are labelled with LMFDB labels.
